Manual align to dcc not working

**louisd** · 05-10-2019, 05:32 PM

Do you have a cad model? If so, here's the easiest way to start using the CMM with CAD. delete that or start a new routine.
load your probe/probe angle you need.
load your CAD model.
press CTL+F4 to turn on "Program Mode".
now. click on the first point -virtually on the cad model, on the screen.
Is the probe in the correct orientation, related to how the part will be fixture onto the table?
--If not, press F5, click on part/machine tab and correct until it does match.
Now, you have your probe looking how it should when taking your first hits on the part, in the virtual cad view.
set the current workplane as you did in the code above.
now still in CTL+F4 program mode, click on your A plane virtually on the CAD model 3 times. Press "END" key on keyboard. you created a plane.

CTL+ALT+A LEVEL and origin X to the new plane.

do the same for your CYL B (5 hits min) and CIR C (3 hits min).
Construct a 2d line from CYL B to CIR C, call it manrotate or something like that.

then CTL+ALT+A again.
Level X to plane A again,
Rotate YPLLUS to manrotate about Xplus
Origin X to plane A
Origin Y to CYL_B
Origin Z to CYL_B
Now rotate your 30 degree offset as you apparently need.

type in mode/dcc
establish a clearance plane or initial movepoint/increment whathaveyou...

Save. Execute. Manually probe the part with your jogbox in exactly the same way you just did virtually on your CAD model.
Cad = Part, you can program anything you want from there. typically autofeatures are ideal from this point on, as they mitigate any vector error induced when you probe constructed points manually using jogbox.

Hello,
After performing my manual align and going to DCC mode, it goes to take the first hit and it is nowhere near where I programmed it to be. I do not understand the disconnect.
Before missing that 1st point it also ignores my move to clear plane and move point. Just goes to PNT_A1 and misses bad.

Please advise.

I added code tags for readability.

I think looking at the things I have changed to red text points to where things go horribly wrong.

When the actuals come out so different than the theoreticals it's bad juju. Something is quite wrong from manual PNT1 onward.

I do not think your alignment method for the manual is the best. I prefer to level, rotate, then set origins. Rotating after setting origin can sometimes cause issues.

There are a lot of other fundamental best practice things I could point out but I don't want to distract you from solving your immediate problem.

I recommend requalifying the probe then I would try recreating the manual hits and alignment from scratch and see if the theos continue to differ from the actuals before proceeding to DCC mode.

HTH (Hope This Helps)

In addition to the previous suggestions, I would point out in your manual alignment:

Code:

A1 =ALIGNMENT/START,RECALL:STARTUP,LIST=YES
ALIGNMENT/LEVEL,XPLUS,PLN1
ALIGNMENT/TRANS,XAXIS,PLN1
ALIGNMENT/TRANS,YAXIS,CIR1
ALIGNMENT/TRANS,ZAXIS,CIR1
ALIGNMENT/ROTATE_CIRCLE,YPLUS,TO,CIR1,AND,CIR2,ABOUT,XPLUS
ALIGNMENT/ROTATE_OFFSET,30,ABOUT,XPLUS
ALIGNMENT/END

If you do not ROTATE immediately after LEVEL, it is a pretty good chance everything that follows after the alignment will be jaspered -up.
Uh.... I just realized Wes has already pointed out the Level|Translate|Rotate sequence is not nice, but figured it is important enough that I'll second the advice!
